The above message contained the following:

The crash log contained the following:

    Thread 0 Crashed:
     #0   0x900740e8 in memmove
     #1   0x0159c09c in ncx_putn_int_int
     #2   0x0159ecc0 in putNCvx_int_int
     #3   0x015a4aec in nc_put_vara_int
     #4   0x015abb70 in nc_put_varm_int

     #6   0x00632b14 in __NF90_PUT_VAR_1D_FOURBYTEINT_in_NETCDF

I backtracked the sequence of function calls to nf_put_varm_int.
Everything looks OK.  In order to proceed further, I need you to create
the file "fortran/fort-varmio.i" and send it to me.  Please do the
following:

    1.  Go into the "fortran/" subdirectory.

    2.  Execute the command

            make fort-varmio.i

    3.  Send me that file.

Also, would you please send me the file "configure.log", which is
described near the end of the file INSTALL.html in the top-level source
directory.

Regards,
Steve Emmerson
